* Allow passing AssociatedData factories in keysutil
This allows the high-level, algorithm-agnostic Encrypt/Decrypt with
Factory to pass in AssociatedData, and potentially take multiple
factories (to allow KMS keys to work). On AEAD ciphers with a relevant
factory, an AssociatedData factory will be used to populate the
AdditionalData field of the SymmetricOpts struct, using it in the AEAD
Seal process.

* Add associated_data to Transit Encrypt/Decrypt API
This allows passing the associated_data (the last AD in AEAD) to
Transit's encrypt/decrypt when using an AEAD cipher (currently
aes128-gcm96, aes256-gcm96, and chacha20-poly1305). We err if this
parameter is passed on non-AEAD ciphers presently.
This associated data can be safely transited in plaintext, without risk
of modifications. In the event of tampering with either the ciphertext
or the associated data, decryption will fail.

* Enforce Minimum cache size for transit backend
* enfore minimum cache size and log a warning during backend construction
* Update documentation for transit backend cache configuration
* Added changelog
* Addressed review feedback and added unit test
* Modify code in pathCacheConfigWrite to make use of the updated cache size
* Updated code to refresh cache size on transit backend without restart
* Update code to acquire read and write locks appropriately
Decrypting an ciphertext where its corresponding value equals empty, the payload property "plaintext" is missing in the response object. This fixes the problem by adding a new, distinct struct for decrypt batch response items where "omitempty" is not set.
This massively simplifies transit locking behavior by pushing some
locking down to the Policy level, and embedding either a local or global
lock in the Policy depending on whether caching is enabled or not.

This ensures that we can safely rotate and modify configuration
parameters with multiple requests in flight.
As a side effect we also get a cache, which should provide a nice
speedup since we don't need to decrypt/deserialize constantly, which
would happen even with the physical LRU.
* Remove raw endpoint from transit
* Add multi-key structure
* Add enable, disable, rewrap, and rotate functionality
* Upgrade functionality, and record creation time of keys in metadata. Add flag in config function to control the minimum decryption version, and enforce that in the decrypt function
* Unit tests for everything
